I’ve had my Kickr Core 4 months and done 4,500km on it. Just the past couple of week it has got really loud (video below), sounds like a turbine winding up, anybody else had the same problem?
I have had to return my core after 13 months and around 5,000 miles. Similar issue, sounded like the bearings were grinding and failing. You should contact Wahoo support. I got a refurbished core sent once fedex confirmed I had shipped my old one.
Had the same noise with my 2nd Kickr Core. It quickly progressed to a loud knocking sound. I interpreted it to be a bearing issue. Fortunately, Wahoo has been pretty good about replacing them, albeit with refurbished units. I’d advise you contact them. Cheers.
Thanks, I had pinged a ticket off to Wahoo too, but being the weekend, was seeing what else people had experienced. They came back today and as you suggest, it looks like they’ll be replacing it.
A friend of mine just replaced the bearings himself as his unit was out of warranty The bearings are easy to source from any online or bricks and mortar outlet. He says it’s never been quieter…
Mine technically was past the 12 month warranty as well, but they replaced it anyway. I asked Wahoo Service if there were any preventative maintenance instruction to prevent this from happening again and they told me not to worry, if it fails again to contact Wahoo Support and they will replace it again… so apparently the warranty is now lifetime?
Edit, still would like to see the process your friend went through to replace his bearings as it is probably faster than waiting for Wahoo to send a replacement.
There’s a video on YouTube of a guy cleaning (with WD40) his bearings. Doesn’t look at all hard to take apart. To be honest, his still sounded noisy to me after, but then as I say, he didn’t replace the bearings. Looks like the sort of thing I could do in years to come if Wahoo don’t keep supporting as well as they seem to be doing this time. They are collecting it on Thursday.
What surprised me watching the video was how much rust colour was coming off his bearings. I wonder if sweat is getting into them?
Thought I’d update on this. Pretty impressed with Wahoo’s service. Within a week of raising the ticket (which I’d done at the same time as my original post) I had a new trainer yesterday, ridden today and much quieter.
Obviously there’s a worry about the longevity now, but can’t fault the service. Was without a unit for just 3 days (each of which I rode IRL instead)
